Patent GB-346004-A (GB)
Title: Improvements in electrical signalling systems
IPC: H04B3/10
Filed: 1930-01-01
Abstract: 346,004. Repeating systems. STANDARD TELEPHONES & CABLES, Ltd. and BONE, R. S., Columbia House, Aldwych, London. Jan. 1, 1930, No. 54. [Class 40 (iv).] In an electric signalling system in which a plurality of devices (e.g. gain regulators) are provided to compensate for changes in the characteristics of the signals when said signals have departed from a predetermined form (e.g. strength) for a predetermined time, the different compensating devices are given substantially different time constants so as to prevent hunting between the compensating devices. The time constants of these devices preferably progressively increase in the direction of transmission so that each device performs its compensating function before the succeeding device commences its compensating function. The Figure shows one form of delay device comprising a valve V the bias of which is removed by relay B under the control of marginal relay A which is operated by rectified pilot carrier current. The operating time constant is varied by varying resistance R through which condenser C discharges when relay B is operated. Alternatively a bi-metal strip type of thermostat may be employed, or the motors or other driving means may be arranged to run at different speeds. In a two-way system the timing of the compensating devices for the east to west circuit is arranged as in a single circuit and the west to east circuit is similarly arranged with the fastest operating device at the transmitting end.

Title: Improvements in or modifications of a process for the production of a low molecular weight glycidyl polyether of a polyhydric phenol
IPC: C07D303/24
Filed: 1960-01-01
Abstract: Glycidyl polyethers of a polyhydric phenol, having more than one glycidyl group and having a molecular weight of less than 500, are made by condensing the polyhydric phenol in the presence of 1 to 10 mol per cent, based on the polyhydric phenol, of a tertiary amine or quaternary ammonium compound at an elevated temperature with an excess of epichlorohydrin to form the chlorohydrin ether, which is then dehydrochlorinated by means of an alkaline material to form the glycidyl polyether, which is subsequently washed free from alkali, the molar ratio of the epichlorohydrin to the polyhydric phenol used being at least 4, the reaction mixture being freed from the excess of the epichlorohydrin after the condensation.  Dihydric phenols such as resorcinol, hydroquinone, 4, 41 - dihydroxy - diphenyl, bis(hydroxyphenyl)methane and 2,2-bis(41 hydroxyphenyl)propane.  The catalyst is preferably used in 10 to 40% by weight aqueous solution. It is preferred to keep the amount of water in the reaction mixture below 25% based on the phenol.  Water may be removed by azeotropic distillation with the epichlorohydrin, the azeotrope separating into two phases and the epichlorohydrin being returned to the reactor. Solvents such as benzene, toluene, acetone, methylethyl ketone, diethyl ether, dioxane and dichlorohydrin may be present.  The molar ratio of epichlorohydrin to phenol is at least 4, and preferably in the range from 6 to 15.  The preferred condensation temperatures are in the range 90 DEG C. to 110 DEG C., the reaction time being generally from 1-5 hours.  Preferably the reaction conditions are so chosen that not more than 1% of the polyhydric phenol remains unreacted.  The condensation may be effected continuously in an extended tubular reactor. Dichlorohydrin and excess epichlorohydrin may be removed by distillation and the catalyst may be removed by water washing. Washing and the subsequent dehydrochlorination are preferably effected at 60 DEG C. to 100 DEG C. 5% aqueous sodium hydroxide may be used as dehydrochlorinating agent, preferably using 10% to 100% by weight excess based on chlorine in the chlorohydrin ether.  The dehydrochlorination is followed by washing to remove the alkali. Detailed examples are given.  Specification 843,575 is referred to.

Title: Shoe component composition
Inventor: HENDRIICKS WILLIS RIDEOUT
IPC: A43B13/04
Filed: 1966-01-04
Abstract: A block copolymer of the general formula A-B-A, in which each A is an independently selected polymer block of a vinyl substituted aromatic hydrocarbon having an average molecular weight between 9000 and 30,000 and B is a polymer block of a conjugated diene hydrocarbon having an average molecular weight between 40,000 and 80,000, or a hydrogenated derivative of said block copolymer, or a composition containing such a copolymer is used as a shoe component and in particular a shoe sole.  The vinyl aromatic compound may be styrene, or a vinyl toluene and the diene butadiene or isoprene.  The block copolymer may be formed by (1) polymerizing styrene in a hydrocarbon medium in the presence of a lithium alkyl to form block A, then introducing a diene and continuing polymerization to give block A-B, and finally introducing styrene continuing polymerization and recovering block polymer A-B-A; (2) as in (1) but in stage two the amount of diene introduced is sufficient only to form a block having half the desired molecular weight, and subsequently a coupling agent is introduced and the desired block polymer A-B-A recovered; or (3) forming initially with a difunctional catalyst such as dilithium naphthalene the diene polymer and thereafter continuing the polymerization in the presence of styrene.  The block copolymer may be compounded with polystyrene, low molecular weight polyalpha methyl styrene, a rubber extending oil, fillers such as soft clay, TiO2, carbon black, whitening, cellulosic fibres, sawdust, or ground cork, and resin-like extenders such as coumarone-indene resins, rosin, petroleum hydrocarbon resins, phenol-formaldehyde, and glycerol esters.  A shoe sole having greater flexibility parallel to the length of the sole than at right-angles thereto is made by extruding the block copolymer or composition thereof, and cutting out the sole shapes suitably aligned.

Abstract: 747,365. Flight training apparatus. COMMUNICATIONS PATENTS, Ltd. Jan. 6, 1954, No. 345/54. Class 4. [Also in Group XXIX] A control apparatus comprises a control member, a piston movable within a cylinder which is adapted to be filled with a fluid, means for producing relative movement of said piston and cylinder in accordance with movement of the control member, a passage which connects portions of the cylinder on opposite sides of the piston and through which the fluid can flow when such relative movement takes place and electro-mechanical means operable to vary the resistance of the passage to said flow whereby the resistance to movement of the control member can be modified in response to an electric signal. In flight training apparatus in which resistance to movement of a control column 1 is increased gradually or prevented to simulate power control failure, the column 1 is connected by a piston rod 2 to a piston 3 of a cylinder 4. The rod 2 enters the cylinder through a gland 5 and an extension 8 of the rod operates in a further gland 9. The ends of the cylinder on opposite sides of the piston 3 are connected by a passage 10 and pipe 13, the passage 10 being formed in a body 15 which accommodates also an axially movable valve 16 operated by a solenoid 17 against the action of a spring 19. The cylinder 4, passage 10 and pipe 13 are full of oil and the coil 18 of the solenoid is energized from a source of electrical energy 22 through a switch 20 and a variable resistor 21. If it is desired to simulate a complete power control failure the switch 20 is closed with the resistor 21 set at its minimum value so that the solenoid moves the valve against the spring 19 to completely block the passage 10 and lock the piston 3 and control column 1. If it is desired to simulate a partial failure only the switch 20 is closed with the resistor set at a selected position. The optimum " open " position of the valve 16 may be selected by an adjustable screw 23.
